PAPER RECEPTACLE AND THE LIKE.

Patented Mar. 7, 1916.

Application filed March to, 1915. Serial No. 18,079.

To all whom it may concern Be it known that I, \VILBUR L. WRIGHT, a citizen of the United States, residing at \Vashington, District of Columbia, have invented certain new and useful Improvements in- Paper Receptacles and the like, of which the following is a specification.

This intention relates to certain improvements in paper bottles and other receptacles; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawings illustrating what I now believe to be the preferred mechanical expression of my invention from among other forms and structures within the spirit and scope stiff material ends applied thereto without weakening or cutting the thin walls.

The invention consists in certain novel features in construction and in combinations and arrangements as more fully and particularly set forth hereinafter.

Referring to the accompanying drawings Figure 1, is a vertical section of a paper receptacle embodying my invention. Fig. 2, is a detail section on an enlarged scale. Fig. 3, is a vertical section of a modified construction. Figs. 4, 5, and 6, are sectional views of modifications. 4

The paper receptacle illustrated comprises athin longitudinal inclosing wall 1, of paper material. T his'wall can be cylindrical, tapered (conical) or of other desired form, and is usually composed of a sheet of comparatively thin paper material folded around a suitable form or mandrel and having its overlapping ends cemented or otherwise secured together to form a longitudinal seam approximately throughout the length of the wall. This wall, after the completion of the receptacle, is preferably suitably treated to render the same stiff and impervious. Suitable ends are applied to this wall to form the bottom and mouth of the receptacle and it is the object of this invention to permanently apply such ends to the wall without danger of weakening or severing the wall and without pinching the edges of the ends into the wall.

In the form typified by the structure of Fig. 1, annular end edges 2, of the wall are composed .of several paper material plies compressed and secured together, the multiply formation being formed by folding the ends of the wall outwardly and back and compressing the same radially against the outer surface of the wall and if so desired, cementing the same th'ereto, thereby forming annular exterior shoulders 3, at the end portions of the wall. These multi-ply end edges and the shoulders thereby provided are utilized in supporting and securing the ends of the receptacle to the wall. The end 4., constitutes the bottom of the receptacle. This bottom is in the form of an imperforate disk of suitable strong stiff sheet material having a surrounding annular depending trough-like portion receiving and embracing the lower end edge of the wall 1, to elevate the bottom and provide the receptacle with an annular depending base rim or flange. although my invention is not so limited. This trough comprises the depending annular wall 5, fitting the inner surface of the wall and the upwardly extending annular wall 7 fitting the outersurface of the wall edge 2, and the inturned bead, edge or flange 6, fitting behind or over the shoulder 3. The opposite end 8 of the receptacle forms the receptacle mouth and is in the form of a trough-like annulus or ring embracing or fitting down around the top edge 2, of the thin paper wall and having its outer lower edge 9 turned in behind the shoulder 3, while its inner lower edge is turned in wardly and approximately horizontally. to form the closure receiving seat or shoulder 10, within the bottle mouth. In the manufacture of the receptacle, these ends are applied in any suitable form to the end edges 2, of the receptacle and any suitable mechanism is employed to tightly clamp or compress the ends on the edges 2, to compress said edges 2. and to turn the flanges 6, 9, inwardly behind the shoulder 3 and to compress thesame thereagainst for permanently locking the ends to the paper wall and to provide tight joints between the ends and the paper wall.

While the ends are preferably composed of sheet metal, yet they can be composed of any suitable sheet material of.the requisite strength having permanent flexion, that is. capable of maintainin itself in the shape or position into which it is bent.

Instead of forming the multi-ply paper material end edges of the wall 1, by doubling back portions of said wall, bands or bushings a, of paper material can be cemented or otherwise secured to the thin wall 1, to provide the end edge enlargements and the annular shoulders, as illustrated by Fig. 5.

nstead of doubling the ends of the thin paper wall 1, back against the outer surfaces of the wall as in Fig. 1, these ends can be doubled back against the inner surface,

of the thin paper wall 1, see 2, Fig, 3, thereby forming the annular shoulders 3 within the receptacle.

\Vith such a formation of multi-ply edges, the bottom 43, is formed with the annular depending trough-like rim to receive and tightly compress the lower edge of the wall 1, and the inner vertical wall 5*, of this rim is expanded radially above the shoulder 3, and into compressing engagement therewith to lock the bottom to the wall 1, and to form a tight joint between the bottom and said wall.

Where the upper end of the thin paper wall is doubled back within said wall as in Fig. 3, the top ring 8, that is compressed on and embraces said top edge, has its inner wall expanded at 9 radially beneath the shoulder 3 and against the same to lock the said ring on the said edge, while the lower end of said wall is turned inwardly to form the closure receiving seat or' shoulder 10. Of course, the shoulders 3 within the receptacle can be formed by placing and securing the paper band (1, within the thin paper wall 1, instead of at the outer surface of said wall.

It will be understood that my invention when applied to the top of a paper receptacle having a thin paper wall, is not limited to the application of a bottom involving my invention to said wall. Also, bottoms involving my invention in thin paper wall receptacles are not limited to receptacles em bodying this invention in their mouth formations.

In Fig. 4, the upper end of the paper wall is formed three ply by providing two portions 2, thereof doubled outwardly and inwardly respectively, to form inner and outer annular shoulders. The metal ring 8", that embraces and is clamped on said three ply paper edge has its outer lower edge 9*, turned up under the outer shoulder, while the inner portion of said ring is expanded at 9, under the inner annular shoulder, and terminates in the flange 10, forming a closure seat.

Fig. 6, shows the upper end of the paper wall formed three ply by the provision of a U-shaped paper ring or Washer 2, embracouter and inner annular shoulders to receive the inturned edge 9, and the expanded portion 9, of ring 8".

It is evident that various changes and modifications might be resorted to Without departing from the spirit and scope of my invention and hence I do not wish to limit myself to the exact disclosures hereof.

\Vhat I claim is:

1. A paper receptacle having a surrounding thin wall of paper with its annular end edge cushioned and formed multi-ply and provided with an annular shoulder facing toward the opposite end of the receptacle by doubling back and annularly compressing the end portion of the thin wall upon itself, and a stifl sheet material end for said receptacle having an annular trough-like por tion fitted over said cushioned doubled edge and fitting the inner and outer surfaces thereof and radially compressing the same to form a tight jointand having an annular locking and compressing portion radially projected under and into compressing en gagement with said shoulder, as and for the purposes substantially as set forth.

2. A paper receptacle having a surrounding thin wall of paper with its annular end edge cushioned and formed multi-ply and provided with an annular exterior shoulder by doubling outwardly and annularly compressing the end portion of the thin wall upon itself, and a stiff sheet material end for said receptacle having an annular trough-like portion fitted over said cushioned doubled edge and radially compressing the same and having an annular free edge turned under and into compressing engagement with said shoulder, substantially as set forth.

3. A paper receptacle having a surrounding thin wall of paper with its annular end edge portion cushioned and provided with an annular shoulder by being formed multiply, and a stiff sheet material end for said receptacle having an annular trough-like portion fitted on said cushioned edge portion and engaging the inner and outer surfacesthereof and compressed thereon and having an annular locking and compressing portion projecting radially under and into compressing and tight-joint-forming engagement with said shoulder, substantially as set forth.

. In testimony whereof I affix my signature in presence of two witnesses.
